Each globe light is equipped with a high-output LED lamp, which delivers more light output than 150 watt PAR38 halogen lamps. Each LED light screws into a molded E26 lamp socket and each socket has hook eyelets. Fifty-one high output PAR38 lamps producing 2,500 lumens per lamp provide a total of 127,500 lumens of bright white illumination. Each lamp housing is constructed from lightweight aluminum and fitted with an impact- and shatter-resistant polycarbonate diffuser. The LED lamps each approximately illuminate a 10- to 12-ft radius with 20-30 ft candles of light when mounted 10- to 15-ft above the work environment. Multiple stringer sections can be daisy chained together via whips terminated in twist lock connectors, with a maximum of four strings chained together providing up to 2,000 ft of illumination.
